Patented Mar. 27, 1934 PATENT OFFHQE WINDOW CLEANER Charles F. Stich, Cleveland, Ohio, assignor to The Marvel Window Cleaner Incorporated, Cleveland, Ohio, a corporation of Ohio Application May 7, 1931, Serial No. 535,581

7 Claims.

My invention relates to an improvement in window cleaners, more particularly of the squeegee type.

An object of my invention is to provide a window cleaning device, which is simple in construction, strong, durable and thoroughly reliable in operation.

Another object of my invention is to provide a Window cleaning device that is economical to manufacture.

Another object of my invention is to provide a window cleaning device that is efilcient, inexpensive and yet substantial in construction.

Another object of my invention is to provide a window washing device, wherein the absorbent cleaning pad and squeegee may readily be replaced.

Other objects of my invention and the invention itself will become apparent from the following description of an embodiment of my inven- 20 tion and by reference to the drawings, illustrates the said embodiment.

Referring to the drawings:

Fig. 1 is a side elevational view of one embodiment of my invention;

Fig. 2 is a vertical cross-sectional view taken through the center;

Fig. 3 is a vertical cross-sectional view of the handle;

Fig. 4 is a bottom view of my invention without the handle;

Fig. 5 is a cross-sectional view of my invention taken along the lines 5-5 of Fig. 4;

Fig. 6 is a sectional view of a joint taken along the lines 66 of Fig. 4;

Fig. 7 is an enlarged cross-sectional view of the joint and squeegee holder with the squeegee in place;

Fig. 8 is a plan view of a spring used in the squeegee holder.

4 The cleaner of my invention comprises a reser voir preferably formed of two aluminum dished sections 1 and 2, respectively, secured together at their corresponding ends by a rolled seam or crimped border edge 3. The rolled seam or crimped border extends along the two sides, and around the two corners 4 and 4' where it terminates abruptly and joins the two flat border flanges 5 and 5 extending outwardly from said dished sections, preferably at an oblique angle to the plane of said body. Flanges 5 and 5 are provided with a series of corresponding perforations 6 lengthwise thereof, preferably elongated openings to receive a series of tongues 7 struck 55 up from the base part 8 of an elongated holder 9 made of metal U-shape in cross section. The ends of the tongues '7 are bent at right angles to clasp and fasten holder 9 to the flanges 5 and 5, and also to secure the two flanges together in fluid-tight union. That is, the two dished body sections are united rigidly together with sealed joints at both ends and at one side, and the holder 9 is adapted to support a squeegee on that side of the device.

The squeegee is preferably made of an elongated strip of rubber 10 of wedge shape in cross section clamped its base end within a corresponding shaped metal channel having side walls 12 adapted to embrace and support the rubber strip 10. This reinforced rubber strip 10 may be inserted into or removed from either end of the channeled holder 9 which has converging side walls to retain the squeegee in place.

A double bowed spring 22 also serves to lock the squeegee member Within the holder 9. This spring 22 is seated within the base part of the holder 9 and has short projections 23 pressed outwardly therefrom and wedged within two of the openings formed in the base part of the holder, where the stock was removed in producing the tongues 7.

The open side of the united body sections 1 and 2 is filled with a flat pad or strip 14 of absorbent material such as felt, this strip being removably clamped in position between two flat border portions of the dished sections 1 and 2, by bolts 15 and nuts 16.

The hollow body may be used as a water reservoir, and the water distributed in the degree required through the absorbent cleaning pad 14.

The filling of this reservoir is effected through a screw-threaded neck 17 formed integrally by drawing operations out of the bottom section 2. The neck 1'7 is also formed to extend axially at an oblique angle to the plane of the section, whereby cleaning operations and the handling of the device are greatly facilitated, and to permit the cleaning pad to be thrust upwardly into corners or around places without bringing the body of the device into contact with overhanging parts on the window, using a handle 18 of any suitble length to manipulate the device. Preferably, the handle 18 is a short piece of metal tubing having the screw threads 19 rolled therein complementary to the screw threads on the neck 17, and a cylindrical piece of cork 20 is wedged within this tubular handle against or into the screw-threaded portion 19, whereby this piece of cork may be brought into pressure engagement with the inturned flange 21 at the outer end of the neck 17 when the handle is screwed to the neck as shown in Fig. 2, thereby effectively sealin the water reservoir within the device when all the parts are assembled and in use.

Having thus described my invention as embodied in a structure of certain specific construction, I am aware that numerous and extensive departures may be made from the embodiment herein illustrated and described, but without departing from the spirit of my invention.

I claim:

1. In a cleaner, a water reservoir, a longitudinally elongated squeegee having converging sides, a channel-formed member carried by the reservoir having channel flan e portions adapted to receive the squeegee therebetween, and resilient means for maintaining the converging side portions of the squeegee in wedging engagement with the said channel flange portions, the resilient means having a stop portion engaging a stop portion of the channel member to prevent relative longitudinal shifting thereof.

2. A cleaner as described in claim 1 and in which the stop portions of the resilient means and the channel member comprise a projection on the resilient member engaging a recess in the channel member.

3. A cleaner as described in claim 1 and in which the resilient means is a spring formed from iiat resilient metal and the stop portion thereof comprises a pair of oppositely extending tongues pressed from the metal and the stop means of the channel member comprises a pair of shoulder portions upon which the tongues abut.

4. In a cleaner, a reservoir comprising two dished sections united at substantially opposi portions by leak-proof seams, and having a pair of flanges extending from corresponding sides iereof, a channeled member for supporting therewithin an elongated squeegee, aligned perforations in the flanges, tongues pressed from the web of the channel, extending through the aligned perforations and bent over to clamp the flanges together in a leak-proof manner, the walls of the channeled member being converging and the squeegee being wedge-shaped in cross-sew tion, resilient means between the base of the squeegee and the web of the channeled member for resiliently wedgingly engaging the squeegee with the channel flanges, the resilient means comprising a spring formed from flat metal and having a projection thereon entering and engaging a shoulder of the channel left by pressing a tongue therefrom to prevent relative longitudinal shifting of the spring.

5. In a cleaner, a reservoir comprising a hollow liquid-containing chamber, a screw threaded neck on the reservoir having a filling entrance in the end thereof, a tubular handle having a screw-threaded end portion adapted to be screwed upon t e neck, and a cork element wedged into the end of the tubular handle at a point spaced from the end thereof adapted to eiTect sealing engagement upon the outer end of the neck substantially at the base of the threaded portion when the handle is screwed onto the reservoir.

6. A cleaner as described in claim 5 and in which the neck is of tubular form and the outer end of the screw-threaded neck is provided with an inwardly radially extending annular flange for sealing engagement with the cork element.

'7. In a cleaner, a water reservoir, a longitudinally elongated squeegee having converging sides, a channel-formed member carried by the reservoir having channel flange portions adapted to receive the squeegee therebetween, and a spring of flat resilient metal for maintaining the converging side portions of the squeegee in wedging engagement with the said channel flange portions, the spring having a stop portion engaging a stop portion of the channel member to prevent relative longitudinal shifting thereof.
